Overview
Shanxi wastewater treatment plant serves the outskirts of Yangquan, Shanxi Province, China, with a population equivalent of 19,000. It discharges into local waterways within the Hai River basin.
The Shanxi wastewater treatment plant is located in the suburbs of Yangquan, in Shanxi Province, China. It serves a population of approximately 19,000 people, classifying it as a small to medium agglomeration under typical Chinese municipal wastewater standards. The plant is situated in a region characterized by a continental monsoon climate, with cold, dry winters and warm, humid summers. As a facility in China, the plant operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for various pollutants. For plants of this scale, secondary treatment with biological nutrient removal is commonly required to meet Class 1-A or 1-B standards, depending on the sensitivity of the receiving water body. Typical facilities in this region employ activated sludge processes. The treated effluent from the plant likely discharges into a tributary of the Hai River system, which flows through northern China and ultimately empties into the Bohai Sea. The Hai River basin is a major water resource for agriculture and industry, and it faces challenges from pollution and water scarcity. The plant plays a role in protecting local water quality and supporting the ecological health of downstream environments.
Environmental context
The plant's effluent enters a tributary of the Hai River, which flows through Shanxi and Hebei provinces before reaching the Bohai Sea. The Hai River basin is a densely populated and industrialized region, making wastewater treatment critical for controlling nutrient and pollutant loads. The downstream environment includes important agricultural areas and coastal ecosystems in the Bohai Sea, which support fisheries and migratory bird populations. Effective treatment helps mitigate eutrophication and protect aquatic life.
